The driving method of the liquid crystal panel 2 may be a simple matrix driving method or an active matrix driving method.

Note that a display panel such as a plasma panel, an organic EL panel, or electronic paper may be used instead of the liquid crystal panel 2. Here, the organic EL panel is a display panel using a substance that emits light when a voltage is applied. Specifically, in the organic EL panel, a light emitting body using an organic material such as diamine is vapor-deposited on a substrate, and display is performed by applying a DC voltage of 5 to 10V. In addition, when an organic EL panel is used instead of the liquid crystal panel 2, a backlight is not necessary.

The first housing 3 includes a base body 31 and a frame body 32. The base 31 has a main surface 31 a, and the liquid crystal panel 2 is provided on the main surface 31 a of the base 31. The frame body 32 is provided on the main surface 31 a of the base 31 so as to surround the liquid crystal panel 2. Examples of the constituent material of the base body 31 and the frame body 32 include resins such as polycarbonate and metals such as stainless steel, aluminum, and magnesium alloys. Note that the base 31 and the frame 32 may be formed integrally or separately.

The touch panel 4 has a front surface 4a and a back surface 4b, and is a detection unit that detects a position operated by a user with a finger or a pen as an input position. As shown in FIGS. 3 to 5, the touch panel 4 is disposed to face the liquid crystal panel 2 with the space S1 therebetween. As shown in FIGS. 1 and 2, the touch panel 4 has a rectangular shape in plan view. In the present specification, even when the outer periphery of the four corners C1 to C4 of the touch panel 4 has an arc shape in plan view, the touch panel 4 has a rectangular shape in plan view. Shall. That is, the touch panel 4 may be substantially rectangular when viewed from above. In the present specification, “substantially” means substantially the same. Here, in the present embodiment, the touch panel 4 uses a capacitive touch panel from the viewpoint of improving detection sensitivity, but instead of the capacitive touch panel, a resistive touch panel, surface acoustic wave, etc. Alternatively, an infrared touch panel, an electromagnetic induction touch panel, or the like may be used.

The support 5 is a member that plays a role of supporting the touch panel 4. The support 5 is provided on the main surface 31 a of the base 31. In the present embodiment, the support 5 is located at a total of six locations including the four corners C1 to C4 of the touch panel 4, the corners C1 and C2, and the corners C3 and C4. The shape of the support 5 is, for example, a cylindrical shape, but may be a prismatic shape or the like. Examples of the constituent material of the support 5 include silicone rubber, urethane rubber, urethane foam, and other rubbers.

The operation unit 6 has a front surface 6a and a back surface 6b, and is a member that plays a role of being input by a user with a finger or a pen. That is, the front surface 6a of the operation unit 6 is a surface directly operated by the user with a finger or a pen. The operation unit 6 is located on the front surface 4a side of the touch panel 4 so as to cover the touch panel 4 in plan view. In the present embodiment, the operation unit 6 is bonded to the front surface 4a of the touch panel 4 through OCA (Optical / Clear / Adhesive). Note that the operation unit 6 may be provided apart from the front surface 4 a of the touch panel 4. The operation unit 6 is translucent. In addition, in this specification, translucency means having transparency with respect to visible light. Examples of the constituent material of the operation unit 6 include synthetic resins such as polyethylene terephthalate, glass, and plastics. The operation unit 6 is preferably formed by forming these materials into a film or reducing the thickness.

The vibrating body 7 is a member that plays a role of bending and vibrating the operation unit 6 when a predetermined input operation by the user is detected. Specifically, the vibrating body 7 repeats expansion and contraction movement in the short side direction of the operation unit 6 (left and right direction when FIG. 1 is viewed from the paper surface), whereby the thickness direction of the operation unit 6 (hereinafter, this direction). Is referred to as “vertical direction”), the operation unit 6 is caused to bend and vibrate. In addition, as will be described in detail later, the vibrating body 7 also has a role of detecting a pressing load on the operation unit 6. The vibrating body 7 is provided on the back surface 6b of the operation unit 6 via an adhesive member (not shown). In the present embodiment, the vibrating body 7 is, for example, a piezoelectric element that performs expansion and contraction based on an applied voltage, but is not limited thereto. An electromagnetic vibrator, a spring, a motor, or the like may be used instead of the piezoelectric element.

In the present embodiment, since the vibrating body 7 is a piezoelectric element, it has the following configuration. That is, the vibrating body 7 is configured by alternately laminating electrodes and active layers, and an inactive layer is provided at a position located near the back surface 6 b of the operation unit 6. Here, the active layer is made of a polarized piezoelectric material. The inactive layer is composed of a piezoelectric material, a metal material, and an insulating material that are not subjected to polarization treatment.

In this embodiment, as shown in FIGS. 1 and 2, two vibrating bodies 7 are provided in the vicinity of both short sides of the operation unit 6 along each short side. In addition, the arrangement position, the number, and the like of the vibrating body 7 are not particularly limited. For example, two vibrating bodies 7 may be provided in the vicinity of both long sides of the operation unit 6 along each long side, or in the vicinity of both of the long sides and short sides of the operation unit 6. Four may be provided along each long side and short side.

The bending portion 8 has a function of bending according to the bending vibration of the operation portion 6. For this reason, the bending part 8 has elasticity. Examples of the constituent material of the bending portion 8 include urethane rubber, urethane resin, urethane foam, silicone rubber, and polyester.

The bending portion 8 supports the operation portion 6. As shown in FIG. 2, the bending portion 8 is provided over the entire circumference of the frame body 32. That is, the bending portion 8 is located between the operation portion 6 and the frame body 32, and the operation portion 6 and the frame body 32 are bonded to each other via the double-sided tape T1. Here, the space S 1 is sealed by the base body 31, the frame body 32, the operation part 6, and the bending part 8. For this reason, in the electronic device X1, it is possible to ensure a certain degree of dustproofness and waterproofness with respect to the liquid crystal panel 2. In addition, in order to ensure waterproofness, it is preferable to use a waterproof double-sided tape as the double-sided tape T1.

Here, the operation of the bending portion 8 will be described. When the vibration body 7 is contracted by applying a voltage to the vibration body 7, as shown by an arrow Y 1 in FIG. 6, the support body 5 serves as a fulcrum and the operation unit 6 and the touch panel 4 are moved downward. Bend. According to the downward curve of the operation unit 6 and the touch panel 4, the bending unit 8 bends upward as indicated by an arrow Y2 in FIG. On the other hand, when the contraction of the vibrating body 7 is released and the vibrating body 7 extends in the short side direction of the operation unit 6, as shown by an arrow Y 3 in FIG. The touch panel 4 is curved upward. According to the upward curve of the operation unit 6 and the touch panel 4, the bending unit 8 bends downward as indicated by an arrow Y4 in FIG.

As described above, the support body 5 serves as a fulcrum, and the operation unit 6 and the touch panel 4 bend and vibrate in the vertical direction, and the bending unit 8 bends in the vertical direction accordingly. In the electronic device X1, since the bending part 8 is provided, possibility that the bending vibration of the operation part 6 and the touch panel 4 will be suppressed can be reduced. For this reason, in the electronic device X1, sufficient tactile sensation can be transmitted to the user.

Further, in this embodiment, since the vibrating body 7 is provided on the back surface 6b of the operation unit 6, the expansion and contraction momentum of the vibrating body 7 is smaller than that in the aspect in which the vibrating body 7 is provided on the back surface 4b of the touch panel 4. Even if it is somewhat small, a sufficient tactile sensation can be transmitted to the user. In other words, a sufficient tactile sensation can be transmitted to the user even if the voltage value to be applied to the vibrating body 7 is small to some extent. This is because the vibrating body 7 is directly provided on the operation unit 6 that is directly operated by the user. Moreover, since the vibrating body 7 is provided on the back surface 6b of the operation unit 6, compared with the aspect in which the vibrating body 7 is provided on the back surface 4b of the touch panel 4, the thickness of the electronic device X1 is equal to the thickness of the vibrating body 7. A1 (see FIG. 4) can be thinned.

In addition, as shown in FIGS. 3 and 5, it is preferable that a gap L 1 is provided between the touch panel 4 and the flexure 8. That is, the gap L 1 is a portion that is not supported by the touch panel 4 and the bending portion 8 in the operation unit 6. In the present embodiment, the vibrating body 7 is located in the gap L1. When the gap L 1 is provided, the operation unit 6 is easily curved and vibrated in the vertical direction due to the expansion and contraction of the vibrating body 7. Here, although the gap L1 depends on the thickness of the operation portion 6, it is preferable that the gap L1 is generally in the range of 0.1 mm to 10 mm.

Next, the operation of the electronic device X1 will be described with reference to FIG.

In the following, an operation example of the electronic device X1 when transmitting a pressing feeling to the user in the tactile transmission will be described. The electronic device X1 is other than the pressing feeling, for example, a feeling of tracing, a feeling of touch, etc. Of course, the present invention can also be applied to transmitting various tactile sensations.

As shown in FIG. 8, when the user presses the touch panel 4 via the operation unit 6, the vibrating body 7 detects a pressing load on the operation unit 6 (Op 1). Here, the load detection function of the vibrating body 7 will be described. That is, when the user presses the touch panel 4 via the operation unit 6, the operation unit 6 is bent downward. When the operation unit 6 is bent downward, the vibrator 7 is also bent downward. That is, the amount of bending of the vibrating body 7 changes according to the pressing load on the operation unit 6. In this embodiment, since the vibrating body 7 is a piezoelectric element, it can be converted into a voltage corresponding to the amount of bending. As a result, the pressing load on the operation unit 6 can be detected by the vibrating body 7. In addition, although the example which implement | achieved the load detection function with the vibrating body 7 was demonstrated above, it may implement | achieve with not only this but load sensors, such as a distortion sensor, for example.

Then, the tactile transmission driver (not shown) determines whether or not the pressing load detected in Op1 is equal to or greater than the threshold when the input operation by the user is a pressing operation on the input object displayed on the display screen. (Op2). Note that the tactile transmission driver is provided on an FPC (Flexible Printed Circuit) connected to the touch panel 4 together with a touch panel driver that controls the touch panel 4.

If the tactile transmission driver determines that the pressing load detected at Op1 is equal to or greater than the threshold (YES at Op2), the tactile transmission driver causes the vibrating body 7 to expand and contract in the short side direction of the operation unit 6 (Op3). Then, the operation unit 6 and the touch panel 4 are curved and vibrated in the vertical direction by the vibrating body 7 expanded and contracted at Op3 (Op4). Thereby, a pressing feeling is transmitted to the user who pressed the touch panel 4 via the operation unit 6. On the other hand, if the tactile sensation transmission driver determines that the pressing load detected at Op1 is less than the threshold (NO at Op2), the process of FIG. 8 ends.

As described above, the electronic device X1 can transmit a sufficient tactile sensation to the user while ensuring a certain degree of dustproofness and waterproofness.

FIG. 9 is a plan view illustrating a schematic configuration of the electronic apparatus X2 according to the present embodiment. FIG. 10 is a plan view illustrating a schematic configuration of the electronic device X2 of FIG. 9 when the electronic device X2 from which the operation unit 6 is omitted is viewed from above. 9 and 10, the same reference numerals are given to configurations having the same functions as those in FIGS. 1 and 2, and detailed descriptions thereof are omitted.

In the electronic device X2, the frame 32 has four corners 32a to 32d. Further, the electronic device X2 includes a bending portion 80 instead of the bending portion 8 described in the first embodiment. The bending portion 80 includes a first portion 80a and a second portion 80b located at the four corners 32a to 32d of the frame body 32 and having a lower degree of bending than the first portion 80a. In the present embodiment, the degree of bending of the first part 80a is 10 to 90%, the degree of bending of the second part 80b is 0 to 70%, and the second part 80b is more flexible than the first part 80a. Is set to be small. That is, the second part 80b is harder than the first part 80a. Note that “deflection” refers to a change in shape of a material. The “degree of deflection” refers to a ratio indicating how much the material changes in shape.

The first portion 80a is located on the outer peripheral portion other than the four corners 32a to 32d of the frame body 32. The second portion 80 b is located at the four corners 32 a to 32 d of the frame body 32. The 2nd site | part 80b is comprised using the material different from the material which comprises the 1st site | part 80a so that the bending degree may become smaller than the 1st site | part 80a. For example, the first portion 80a is made of silicone rubber, urethane rubber, urethane resin, polyester, or the like, and the second portion 80b is made of silicone rubber, urethane rubber, polyester, or the like.

In addition, you may comprise the 2nd site | part 80b so that a bending degree may become smaller than the 1st site | part 80a by making a shape different in the 1st site | part 80a and the 2nd site | part 80b. For example, the first part 80a is configured in an M shape when viewed in cross section, and the second part 80b is configured in a rectangular shape when viewed in cross section. When the first part 80a is M-shaped when viewed in cross section, the first part 80a expands and contracts according to the bending vibration of the operation unit 6, and the bending vibration of the operation unit 6 is urged by the expanding and contracting force. It is preferable because it becomes possible. Because the shape is M-shaped, when the first portion 80a contracts, the force to repel the contraction is larger than other shapes. The first portion 80a may have a U shape when viewed in cross section, or may have a hollow shape inside.

As described above, in the present embodiment, the first portion 80a is located on the outer peripheral portion other than the four corners 32a to 32d of the frame body 32, and the second portion 80b is less bent than the first portion 80a. Are located at the four corners 32 a to 32 d of the frame 32. Therefore, when the operation unit 6 is caused to bend and vibrate in the vertical direction by the expansion and contraction of the vibrating body 7, the second portions 80b located at the four corners 32a to 32d of the frame body 32 serve as fulcrums, The operation unit 6 can sufficiently bend and vibrate in the vertical direction. Therefore, compared with the electronic device X1, the electronic device X2 can transmit a sufficient tactile sensation to the user.

As described above, the electronic device X2 can transmit a sufficient tactile sensation to the user while ensuring a certain degree of dustproofness and waterproofness.

In the present embodiment, the bending portion 80 includes the first portion 80a and the second portion 80b that is located at the four corners 32a to 32d of the frame 32 and has a smaller degree of bending than the first portion 80a. Therefore, the support 5 is not necessarily provided.

In the present embodiment, the example in which the second portion 80b is positioned at the four corners 32a to 32d of the frame 32 has been described, but the present invention is not limited to this. In addition to being located at the four corners 32a to 32d of the frame 32, the second part 80b may be located between the

corners

32a and 32b and between the corners 32c and 32d.

In the electronic device X3, the frame 32 has a groove 321. Further, the electronic device X3 includes a stopper 11 that prevents the operation unit 6 from being detached from the frame body 32. The stopper 11 is inserted into the groove 321 of the frame body 32. As a constituent material of the stopper 11, the same constituent material as that of the first housing 3 can be used. Here, consider a case where force is applied to the electronic device X3 from the outside, such as when the electronic device X3 falls. In this case, there is a possibility that the double-sided tape T1 positioned between the operation unit 6 and the bending portion 8 or the double-sided tape T1 positioned between the bending portion 8 and the frame 32 may be peeled off. When the double-sided tape T1 is peeled off, the operation unit 6 may be detached from the frame body 32. However, in the present embodiment, even when a force is applied in the direction indicated by the arrow Y5 in FIG. Since the stopper 11 comes into contact with the inner surface of the groove portion 321 of the frame body 32, the electronic device X 3 can prevent the operation portion 6 from being detached from the frame body 32.

As described above, the electronic device X3 can transmit a sufficient tactile sensation to the user while ensuring a certain degree of dustproofness and waterproofness. In the electronic device X3, the reliability is improved.

The electronic device X4 includes a support body 50 instead of the support body 5 described in the first embodiment. In the present embodiment, the diameter M1 of the surface 50a that contacts the back surface 4b of the touch panel 4 of the support 50 is smaller than the diameter M2 of the surface 50b that contacts the main surface 31a of the base 31 of the support 50. A body 50 is constructed. Specifically, the support 50 has a so-called tapered shape in which the diameter gradually increases from the back surface 4 b of the touch panel 4 toward the main surface 31 a of the base 31. If the support body 50 is comprised in this way, the restraint degree of the touch panel 4 by the support body 50 can be reduced. For this reason, in the electronic device X4, sufficient tactile sensation can be transmitted to the user.

It should be noted that the “surface diameter” mentioned above means the diameter of the circle when the surface is circular in plan view. Further, the “diameter of the surface” mentioned above means a diagonal line of the polygon when the surface is polygonal when viewed in plan.

As described above, the electronic device X4 can transmit a sufficient tactile sensation to the user while ensuring a certain degree of dustproofness and waterproofness.

That is, by placing a finger on the liquid crystal panel 12 via the operation unit 6 in a state where external light is incident on the light detection unit, external light incident on the light detection unit corresponding to the finger is blocked. Is done. Thereby, in the liquid crystal panel 12, the input position can be detected by comparing the detection level of the light detection unit in which external light is incident with the detection level of the light detection unit in which no external light is incident. it can.

In addition, although the example of the liquid crystal panel 12 provided with the light detection unit as the liquid crystal panel having the input position detection function has been described above, the present invention is not limited thereto. For example, a liquid crystal panel in which detection electrodes in a capacitive touch panel are formed on a substrate on the liquid crystal panel side may be used.

As described above, the electronic device X5 can transmit a sufficient tactile sensation to the user while ensuring a certain degree of dustproofness and waterproofness. In addition, since the electronic device X5 includes the liquid crystal panel 12 having the input position detection function, it is not necessary to separately provide a touch panel, and the electronic device X5 can be downsized.
